ADEKAN

Shirou, a laid-back and absentmindedly seductive umbrella craftsman, is (surprisingly) a close friend of Koujirou, a hot-blooded young police officer who stands against all things undisciplined. With their mutual knack for attracting trouble, the pair soon find themselves involved in a bloody and erotic thrill-ride in their off-kilter town full of equally off-kilter people. This action-packed, jack-of-all-trades manga will have you swooning at its sexiness and leave you more addicted than opium—guaranteed! — Description from AniList community (anilist.co).
